In other words, if you suspect that there may be more than one cointegrating relationship, applying ARDL is not appropriate, and the Johansen cointegrating approach should be used. I don't know what papers you are referring to, but if they are not respecting the assumptions of the ARDL cointegrating model, their analysis will not be correct.IHSEViewshttps://www.blogger.com/profile/04703437003033046408noreply@blogger.comtag:blogger.com,1999:blog-6883247404678549489.post-40785808403491617812018-05-21T14:31:33.040-07:002018-05-21T14:31:33.040-07:00(Assumption 3)No feedback from

It was extensively studied in Banerjee, Dolado, Mestre (1998), and is therefore often called the BDM test.<br /><br />To answer your question formally would require a huge amount of theory. However, in a nutshell, both BDM (1998) and PSS (2001) papers argue that asymptotically, the t-statistic cannot distinguish between Cases I and II, and III and IV, respectively. In other words, whether deterministic restrictions are imposed or not, the limiting distribution of the t-statistic will be invariant to these restrictions.IHSEViewshttps://www.blogger.com/profile/04703437003033046408noreply@blogger.comtag:blogger.com,1999:blog-6883247404678549489.post-84508017764214518252017-09-29T06:10:49.896-07:002017-09-29T06:10:49.896-07:00Dear all,

Specifically it is r_x if phi_yy(1)=0 and r_x+1 if phi_yy(1) is not equal to zero.
